This video summarizes science and data obtained by the Upper Atmosphere Research Satellite (UARS) mission. UARS was launched in 1991 to study ozone depletion and the processes that control the stratospheric ozone layer. Although the mission was intended to last only 18 months, UARS continued to operate 7.5 years after launch with 8 of the 10 instruments at the time this video was made. UARS has been one of the most successful NASA satellite programs. The spacecraft was developed and is managed by NASA's Goddard Space Flight Center. Note: The entire narrated UARS video.
